Biography
Gofraid ua Imair was a grandson of Ivar the Boneless and a cousin of Ragnall ua Imair and Sihtric Caech, and he and the other Vikings were forced to flee Dublin in 902. He helped his cousin Ragnall conquer Northumbria in northern England, and, when Sihtric became King of Northymbre in 921, he gave Gofraid the Kingdom of Dublin. Sihtric launched several raids against the Irish, notably at Armagh, and, in 927, he left for Northymbre after Sihtric's death. Sihtric's sons felt cheated, and they seized Limerick, leading to a period of conflict between the Norse settlers of Dublin and Limerick. Gofraid was driven out of Northumbria by Aethelstan of England within six months of his arrival, and he returned to Dublin to eject the sons of Sihtric, continuing to rule as king there. He then led raids on Kildare and Dunmore Cave, and he defeated the rival Vikings at Mag Raigne in 931. He died in 934.
